Looking to create a website with a gallery block but running into some issues. I only want to utilize Bootstrap along with my custom CSS for the finishing touches. The layout should consist of 2 squares next to each other, with the left square being 2 columns and 2 rows, and the right square taking up the same space as the left one. Similar to the image provided.
I've attempted various methods including flexbox, but haven't been able to achieve the desired result.
